Xcomunic8d-
Please see the PM I sent responding to your CG questions.

Thanks terry.

You have convinced me to put it back to an I/O. Now for more research... on hp ratings and performance reports.

An I/O with a duoprop would do wonders on that hull. A good friend with a 23 had that set up with a 502 BB Chevy. Breathtaking acceleration and effortless cruise.

Ty Moose. I appreciate the input. The calculators I keep seeing them tell me I’ll do 53knots or 60mph. It seems a bit high to me.

I’ve got a 5.3 LMG being delivered tomorrow. Best part-it was free. It belongs to a friend who’s moving off island. I’ve got to tear it down and see what I find. Otherwise I was going to build a merc’d 383 stroker.

To do list:
Afm delete
Lifters
Push rods
Check the lower end (piston rings, bore, etc).
Clean and port heads if decent otherwise new ones and do that
New cam
Water pump
Oil pump
LS marine headers
Engine mounts
Oil filter relocation
Control box

I anticipate making 400ish hp. I was originally planning on 500 just because that’s what it had maxed out originally. But that would for sure eliminate my option of an alpha drive. I’ve been told as long as I don’t jump on throttle it should be ok. I’m keeping an eye out for a good deal and if the price is right I’ll go bravo for sure. But if I can get an alpha for 1k, I can always flip it on Craigslist.

Those bravo 3’s do look mighty nice...

The volvo drives are not anywhere near the quality they used to be famous for, seals are very leaky(bad personal experience with 3 sx duoprop drives). The Bravo 3 is supposed to be a great drive and I agree with kmoose, the duoprop format is perfect for the 25.

The 25 is so sharp and deep that the available calculators probably don't calculate top speed correctly. I agree with you on speed.

Engine rebuild memory
 

Hi Xcomunic8d
Your plans for rebuilding the engine brought back fond memories. In late 1969 I bought a ’68 Corvette which I owned for 30 years. About 1984 I did a rebuild of the 350 Hp 327 where I replaced about everything except the block, crank and connecting rods. I took my time and did some things that may not have been necessary like line boring and balancing of parts; but wanted no regrets when I was done and in the event I never rebuilt another- which I never did. The engine was still quite strong when I was hit in 1999 by a Suburban totaling it. A funny thing though, right after the initial engine firing my heart sank when I saw antifreeze leaking. My relief when I realized I had installed the thermostat by hand to keep the threads clean when I painted the cylinder head.
